FWIW I’ve had good luck implementing APIs with Cowboy or Plug in commercial projects. The consumers of the APIs were either single page apps (React, Angular) or third-party backends. In those cases we didn’t need all the extra features that come along with Phoenix so we opted for the lighter approach.
Since you’re new to Elixir, I recommend picking 2 or 3 libraries/frameworks to evaluate a small part of your app in and getting hands-on experience with each one. Not only will that give you a better idea of each library, you’ll gain more experience with the Elixir language and ecosystem as well.
If you need to interface with exchanges via UDP or provide a UDP connection to your clients, check out the documentation for gen_udp.

The new keynote from Elixirconf 2018 might give you another reason on why to use Phoenix.

No UDP with phoenix, yes UDP with cowboy. Cowboy is pluggable and it supports theoretically any transportation formats, like HTTP via TCP is via ranch as I recall (or was that the other way around…). ^.^
